I lost my wall charger that came with my HP touchpad. The round plug thingie is what I'm looking for. Searching on Amazon brings up a number of items, for example:
http://www.amazon.com/HP-North-American-Charger-TouchPad/dp/B0055QYJJM/ref=dp_cp_ob_e_title_3
However, is there an alternative that works? I was able to use the Evo cable rather than the original HP sync/charge cable that came with the wall charger, but is there an alternative wall plug that works as well? Paying almost $28 for a charging cable seems a bit ridiculous.
Any help and advice would be most appreciated.
[[FOUND MY ANSWER]]
I found that Walmart was having a sale on the North American charger with the barrel wall connector for $11.99 and Meritline was having a sale for 6' long USB to micro-usb cables (pair for $4.99 no tax/shipping).
The listing on the Meritline page says that the cables are compatible with the Evo.
Given that the cable that comes with the HP barrel charger is pretty much monkey spit and fails within a month, I found a solution that works for less than $20.

Meritline Cables (use this code MLCK222YNL1 for discount (cannot guarantee how long this code is good for, drops the price for a twin pack of the 6' cables from $10.99 to $4.99)

Pretty much any USB charger will work, but most give a notification on the Touchpad screen indicating that they may not be charging. This is because the official charger is at the high end of both voltage and current capability. I charge from laptop, desktop and a variety of Blackberry chargers with no issue, but the available current will determine how long it takes to charge and whether it charges much while the screen is on. Go for a USB charger that gives you 2 Amps and you should be fine.

Thank you for the advice. To be more specific, can you recommend any alternative charging cables/wall charger units specifically?
Any brand name USB charger that gives off 2 amps should be fine. I tend to stay away from really cheap generic chargers. Any microUSB cable should be fine even a generic one if it has decent reviews. I worry about generic chargers since a poorly regulated one could send a voltage too high, but generic cables should be fine.
The chargers I am currently using, as well as the one that came with the TP, are the one that came with a Blackberry Playbook and the one from my HTC Desire HD.
The Blackberry charger gives an error on the screen that it may not charge the TP, but as it gives 2 amps, charges in pretty much the same time as the official unit.
The HTC again gives the warning and takes about twice as long to charge.
what about the nook color charger i know it higher amps might work as well

I just tested the TP with a charger for the NC, and unfortunately, it still gives the same "may not charge" warning...
There is NO after market charger that will charge at full rate like the HP barrel charger!
At best they will trickle charge at a much lower rate and take considerably longer to charge.
The TP relies on precise signaling which it will only get from the OEM item or specially modded after market units or cables.
Do a google for further info ie webosnation.com forums.
I think your looking for a 5.1v charger, aka rapid charger. This is used by the iPad, and some android phones like the Motorola droid 3, razr and htc rezound.
I could be wrong though,I haven't gotten my touchpad yet.but I do own all said device above (except the razr) and they all use the faster charging technology.

Don't believe all the hype about using ONLY the HP charger, there are many that do the job perfectly well. Too many people make these authoritarian statements and all they do is cause FUD.
At my office, I use the AC charger from my last Samsung phone (mythic) and it works IDENTICALLY to the OEM one. I have also used a Moto and and LG with NO PROBLEMS. I have no issues getting to fully charged in little time.
At home, my OEM cable is plugged into a high-power USB port (2.1A, I believe) and it has no problem charging from near zero to full as well. Front or top-mounted USB ports tend to be 500mA or less, but the rear ones (coming directly off the motherboard) tend to have a higher supply. I also use a non-HP USB cable occasionally and it works fine.
(I got my TP during the original fire-sale and have been charging it these ways ever since with ZERO ISSUES.)

The small voltage difference is marginal and isn't going to matter, the internal hardware should be able to tolerate a few tenths of a volt difference. In fact, I tested my Motorola charger rated at 5.1v and the Touchpad charger rated at 5.2v on a multimeter. The Motorola charger was outputting 5.20v and the Touchpad charger 5.16v. Granted this is at no load, but switching transformers are regulated so they should supply rated voltage at any current draw equal to or less than rated. Also depending on how well the voltage is regulated there may still be a slight AC ripple that the device has to deal with.
Does anyone know the time difference between using the TP charger and a standard droid/blackberry charger? Also curious if the charges last the same. I know theoretically they should since the battery is full either way, but electricals can be tricksiy..

Its all down to the charge rate that the TP is able to draw.
2A which is theoretically possible from TP AC barrel charger would charge the 6A+ battery of the TP from flat to full in approximately 6.5 hours.
If the BB charger were able to have 500mA drawn by the TP then it would fully charge in approximately 26 hours.
The charges would be no different.
To convert any regular USB charger into a TouchPad charger you need to add 2 resistors as per the diagram attached.
The presence of the resistors will trigger the TouchPad to draw the full 2A from the charger rather than the trickle charge it does when they are not there.
Please do not modify a cheap charger that is only rated for 500mA as you will most likely overheat it and it could present a fire risk.

Just pointing out that you need to start with a charger that is rated at least 2Ah to start with.
You can't turn a low rated one into a high rated one.

oh, for the love of gods. REALLY? I was just asking for a replacement cable. I don't want to reinvent the charging paradigm. I just need a simple recommendation for a cable. If a thread could be highjacked any further I don't know how it could be.
I appreciate all your "advice" but seriously, this is NOT what I was asking.
Anyone know if I can get a similar cable in the UK? Kind of lost my TP cable, and I miss the flexibility the long cable gave me, it was so much easier to use on charge!
well i know that my tbolt cable works. i have to use the tp adapter though. my tbolt adapter makes the touchpad say that the charger is incompatible.
Hi.
I'm looking for an advise about car charger that can charge my TF700.
does anyone confirmed that there any car charger that works?
I mean, I saw some posts that says that ASUS' charger is 15v instead of the more common 5v?
but then I saw the charger, it says " Output : 5v === 2A or 15v === 1.2A"
So I assume I can use other car charger that works with other tablets?
can someone confirm this for me?
THANKS
The tablet will only start to detect a charge at 12V.
Charging at anything lower than that will charge about 1-3% every hour.

oh. okay. any recommendation on what charger should i get?
preferably one with dual USB.
USB is not going to work, in any form or capacity. a USB port can only put out 5V at max.
I use a power inverter that puts out 230V (bought it for my laptop a couple of years ago) through a normal outlet. Plugged the charger into that and it charges normally. You could try looking into that.

YES the ASUS Transformer will only charge from between 12 & 15V. They DO NOT charge from 5V USB.
I have found that the car chargers which have the ASUS 40 pin plug attached to the cable work fine. They have a regulator circuit which outputs 12V at 1.5A minimum.
The ones available on eBay work well and aren't too expensive. They are a little bulky because of the high current circuitry so look at the pictures and make sure that it looks bigger than the average ones and you will do fine.
unfortunately there's no car charger available as of yet.

An Carcharger is avilable, i have one and it is working. 15v 1,2A Carcharger with normal Asus connetor. I'm usin it since 2 Month, never had problems. Carcharger is even cooler as the 230V USB charger while charging. Asus Tabel also switch immediately in charging mode. 14€ at Amazon.de.
By the way, why is everyone saying 5V won't work? On my 230V USB charger there's following note "15V 1,2A or 5V 2A"
Well won't need it, just buy this one ( which i have):
www.Amazon.de/gp/product/B007PQ8AN6/ref=oh_details_o04_s00_i01
Just ignore that tf700t isn't written there and that the charger would have 1,5A. Thats wrong, Carcharger has 15V 1,2A.
If you won't believe me, i can make an picture ( that it will have 15V 1,2A and works) otherwise have fun with it

Why aren't you reading everything? I said 5V charges too slowly for the tablet to detect, but it does charge. About 1-3% an hour, which is useless when you're using it. It clearly says, in the manual, that it will only charge over USB (5V) when turned OFF and not connected to the dock. RTFM.

I don't know how many different threads I have to post this in...
http://www.amazon.com/gp/product/B0081BFYY2/ref=wms_ohs_product
Includes a home charger, car charger, and an extra USB cable, that ALL work. I have been using these with my Transformer Prime, and now my Infinity without an issue at all, and they provide the ASUS required specs for charging and work just like the factory provided chargers.
I ran into this issue with my Verizon Samsung Galaxy Nexus. When attached to a charger, if I went into Settings...Battery... it would show the status of the charging process: it would say "USB" when connected to a computer, and charged at a much slower rate, or "AC" when plugged into the supplied charger in a regular outlet, and charged much more quickly.
With most car chargers, it would only show "USB" but there are some car chargers that have the correct wiring so that it was recognized as "AC" and charged as quickly as when plugged into a regular outlet.
I have two of these in my vehicles, and I just checked one of them, the one listed below first, and with the Tablet plugged into it, it shows as charging, as an "AC" source, just as with my Galaxy Nexus.
Here is the one I specifically tested and verified that it works:
Dual USB Car Charger
I do note the 2 negative reviews there, but all I can say is that I've had this one for almost a year, and it has worked perfectly for me with my phone. A brief test with the Asus Tablet confirmed it was seen as an "AC" charger.
This is the other one I have and which works fine with my phone, although I have not specifically tested it with the Tablet (I have no reason to expect it would behave any differently):
HTC T-Mobile myTouch 3G Car Charger
Obviously, I can't be held responsible if somebody else has a different experience with these, or has problems because of it. Just trying to be helpful and report what has worked for me.
You might consider the i-Blason 12V 2A MINI BULLET STYLE CAR CHARGER FOR ASUS Eee TRANSFORMER from Amazon (Sorry, but noobs can post links)
It's compact, uses your existing cable and delivers 12 VDC @ 2 A. Under $10 US.

It may work, or it may not. Drawing on my experience with the Galaxy Nexus, there were quite a few car chargers that had specs like this but which in fact were seen as "USB" chargers when used with the Nexus, and I suspect would behave the same way with the TF700T.
I am not an eletrical engineer, but it has something to do with how certain pins are shorted or not, and not all chargers that say they deliver the higher amperage will in fact do so with all devices.
It'll just take somebody to buy and try, and report what does or doesn't work. Per my post above, the chargers that work with my Nexus also work with my Tablet, in being seen as "AC" charging.

I have one on order and will pick it up at my daughter's when we go to the US next month. Will post what I learn.
HOWEVER - a true "USB Charger" provides a 5VDC output, not 12- 15 VDC, as does the i-Blason unit I mentioned. Note that i-Blason states very clearly, "Warning: Pls do not use with other MP3 or smartphone... High Voltage could cause burn out."
The difference many smartphones (and other USB ported devices) detect in "USB Chargers" versus "AC Chargers" is max current available (<0.5 A vs >1.0 A) For example, I have a USB battery and a video cam that will both fail to illuminate the charging light if connected to a charging source below about 0.75 A, but still charge, albeit slowly. Both came with 1.5 A USB (5 VDC) wall chargers.
Since the i-Blason is a 12 VDC, not a 5 VDC output, the odds are high it will charge the Transformers at a rate very similar to the wall charger. At least based on electrical "theory". If I had to blind pick a third party car charger, the specs for the i-Blason, to include using the stock cable, were what influenced my choice.

Appreciate the additional info - will be interested to see if it performs as hoped. I suspect it will, especially based on that warning.
My moto g (1st gen) is about to arrive but I don't know how to charge it yet. I heard it takes long to charge in PC and I need a wall adapter for charging on the go anyways. Original brand ones are really expensive and I want to avoid that cost if possible. So is it safe to use a generic (most likely without any brand) wall adapter? For example one that says 100-240VAC, 50-60 Hz Output 5.0VDC 1.2mah. If not, what should I take into account when looking for a charger?
Thanks in advance.
It's not necessary to use original moto charger but it's recommended you can use any other chargers for charging With appropriate Voltage values...
Sent from my XT1033
All USB chargers have a regulated output voltage of 5 volts DC, and all of them are compatible with any device that charges via a USB/mini/micro port.
The difference is the maximum charging current, which generally ranges from a low of 300 milliamps to a high of 2 amps. More current will fill up the battery faster, as long as the charging control circuit on the device will accept more power. Regular USB ports like the ones on your computer are specified to put out a maximum of 500 milliamps current, so most device charging circuits will detect when they are on a computer USB port and limit their current drain to 500 milliamps to avoid triggering a "port overload" shutdown on the computer.
Devices with big batteries (like tablets) will take a long time to charge with a low-capacity charger, so you generally want to use a higher-capacity 2 amp charger with those to cut the charging time. Phones are generally somewhere in the middle - they'll charge in a reasonable time with a 1 amp charger, but they might benefit from using a 2 amp charger. You can still charge them using a low-capacity charger or a computer USB port, but you may need to shut the device off while charging if it consumes more battery power in normal operation than the charger can pump into it. And it might take a very long time (like 24 hours) to charge a big battery from a small charger.

Yes I'm aware of all this. The thing is I purchased it from Amazon and it doesn't come with a charger. That's why I need to purchase one. I know it works without problems with samsung, htc, blackberry, etc chargers but I don't know if it works -without problems and risks- with a generic charger. By generic I mean those chinese cheap ones that "imitate" original ones. So are those safe? Thanks again.
There's generally no problem with an inexpensive generic charger, but cheap junk is cheap junk. If it costs $1.99, and the connections are poorly soldered, the components are under-specified, and the construction quality is generally shoddy, then sure it can easily break, overheat, or go up in smoke. It could even conceivably damage your connected device. Just use some common sense in evaluating when something is too cheap.
I just got a samsung charger which seems to be for the note 2.. My worry is that I'm not entirely sure if it's original (even though build quality seems good) or not because of many reasons: a) I just noticed the model on the box (eta0u10ebecstd) is different than what is printed on the charger (eta-u90ewe) , including amperage listed (0.7a on box, 2a on charger) even though the box had the security seal b) I google'd about the model in the charger and I only saw it with the european plug presentation, didn't see a single american plug of that model (and I have the american plug). c) there seems to be 2 "presentations" with different printings (what varies is the location of the certification logos mainly and 1 extra certification for each "model" the other one doesn't have)
So my question is simple: Let's suppose the charger is not original, can it damage my phone? Thanks again.

If it is not Genuine avoide using as much as you can.
Using a genuine Samsung with Motorola or any charger made by real maunfacturer (Nokia, Samsung, LG, HTC.... etc) with any other phone is ok
but a duplicate charger is always a risk, because you never know what has been compromised.
Alright, I'll get a genuine one asap. Any tips to differentiate between an oem or duplicate charger?
"Genuine" is not a word that applies to USB chargers. Perhaps you mean "same brand as my phone", or "recognized brand name". That's one way to be sure you're getting acceptable quality. But you'll save some money if you just use common sense in evaluating the price and quality of what you're buying. There's nothing wrong with most generic USB chargers, and there's certainly no problem using a different brand-name USB charger with your phone.

There are ways to differentiate then, but you need to measure the output under load and see if there is noise and ripple with an oscilloscope, which is not in everyone's possibilities.
Best way to get a genuine charger for cheap is to buy it from a friend who has it from some old phone. Or just look for brands like Nokia, Sony, Hama, Belkin, Energizer etc in some trusted sellers like Amazon or big local hypermarket.

Powergen afaik are making high-power output chargers.You'd be fine with one of theirs, their quality is airtight and the prices are good.
Hi,
Wanted your thoughts and opinions on charging speeds. I've never actually timed how long it takes to charge. i leave it overnight and it's ready when i wake up.
When i plug the phone into the charger, it flashes up slow charging for 2 seconds then disappears. which got me wondering how much it's actually using.
i used to use Current Widget app on my Samsung S3 which told me exactly how much current the phone was taking from the charger. typically it was 1A via AC/mains and 499mA from a PC. Plugged in to AC, I could play a power hungry game and it would still charge the phone at a good rate.
The LG kernel doesn't like these apps - the mA value is all over the place but it's typically <500mA displayed.
I could buy a USB ammeter to work out how much the USB charger is supplying but do you have any other methods of finding out? Do you know what your phone uses?
at home, i use a Xtrememac dual USB charger, 2x 2.1A output with a shielded 3M USB cable. for those wondering, it's the same regardless what cable i use. Have also tried with generic usb chargers, iPad chargers and official and OEM cables from LG and various other manufacturers. Have also used a data-shorted USB cable from PC which is the same result.
I haven't tried the LG charger yet (mainly as it's a 2 flat-pin plug and i don't know where i put the box) but i think i recall it being a 1.8A charger.
I use an application called "charger report" which can display current consumption and Xtar "USB detector" device. They both show the same numbers. But Xtar USB detector can detect voltage of a charger. The charging current of LG g pro 2 is 1.4-1.5A when the smartphone is not used and higher when I use it. Using USB detector I found out that this smartphone can charge with maximum current a charger can give only if the charger's voltage is 5.3v. So it chargers at full speed with original charger and two other chargers I have: a charger from my Lenovo s6000 (2A 5.4V) and from my Asus t100 (2A 5.3V).
i tried that app too and got the same results as with Current Widget.
i'll buy a "usb detector". thanks.
I forgot to mention that it take approximately two hours for charging indicator to reach 100% when the smartphone reports that it fully charged. And it's necessary to left it connected to a charger for ten to twenty minutes to be really fully charged. Otherwise charging indicator will soon drop to 90%. One can tell if a smartphone is still charging by touching a charger or by looking at current consumption: a charger would be warm and current would be higher than 200mA.
Is the GP2 Quick Charge (1 or 2) enabled? I can't read anything about it other than it's in Snapdragon chipsets. Not sure if it can be disabled or not.

The Snapdragon 800,801 and 805 is for Quick Charge 2.0
The Snapdragon 600 for 1.0
ok, does anyone use a Quick Charger with their GP2? is it noticeably faster?
not yet available in Austria, I have read it kills the battery life on

Hi,
Wanted your thoughts and opinions on charging speeds. I've never actually timed how long it takes to charge. i leave it overnight and it's ready when i wake up.
When i plug the phone into the charger, it flashes up slow charging for 2 seconds then disappears. which got me wondering how much it's actually using.
i used to use Current Widget app on my Samsung S3 which told me exactly how much current the phone was taking from the charger. typically it was 1A via AC/mains and 499mA from a PC. Plugged in to AC, I could play a power hungry game and it would still charge the phone at a good rate.
The LG kernel doesn't like these apps - the mA value is all over the place but it's typically <500mA displayed.
I could buy a USB ammeter to work out how much the USB charger is supplying but do you have any other methods of finding out? Do you know what your phone uses?
at home, i use a Xtrememac dual USB charger, 2x 2.1A output with a shielded 3M USB cable. for those wondering, it's the same regardless what cable i use. Have also tried with generic usb chargers, iPad chargers and official and OEM cables from LG and various other manufacturers. Have also used a data-shorted USB cable from PC which is the same result.
I haven't tried the LG charger yet (mainly as it's a 2 flat-pin plug and i don't know where i put the box) but i think i recall it being a 1.8A charger.

Hey ray-lee!
I just bought this phone and as it seems it could get someday similar problems as my former phone the Galaxy Note 2.
That phone has had problems with charger and cable also. I had to buy another set of charger and cable since the original ones gave up a few months after i purchased the phone (it was used). The cable managed only 500mA wich is very slow for a battery that strong. One night was once not enough to charge my phone from 30% to 100%. As it seems it is problematic to manufacture cables, that can hold up and continually grant the 1,8 A that would charge our device in just 2 hours. I read somewhere that the G Pro 2 is one of 5 devices that has blazing fast speeds on charging the battery. If you handle the cables with caution hopefully you will not encounter problems. If so my guess is, that you will have a hard time in finding a cable that can hold up. Sadly the stock cables are always more expensive. I do not get it, why companies dont build travel adapters that only charge ur phones built solid with sturdy cables to ensure the transmission of high currents. That way with charger + usb cable is just stupid, even when tis is an all in one solution.
I like this phone very much and i hope, that the cables will not be that sloppy as the cables that Samsung had/ still has. With Current Widget i get readings around 1500 mA (1,5 A) when connected to the stock charger. And yes the LG Charger is an 1,8 A one. I have also flat pins, but received an adapter to be able to connect it in Hugary.
Just sharing thoughts here, that will maybe helpful to someone...
:highfive:
2amp charger, charges my Pro 2 in apprx 1 hour while my old LG 1amp charger fills it in 1.40 hours apprx

i "think" as long as device has snapdragon it is Quick Charge enabled
I use the "Charging Report" app on my phone, and it reports proper values.
(Around 1500mAh with the LG charger, and around 1600mAh with the 2.0A Samsung charger.)
If your phone is charging slowly, check the CABLE. Cable can broke too.
(Many people complain about their Samsung charging cables, because they just stop delivering power after a while and just charge the device slowly.)
Anyone tried Quick charge 2.0?? https://www.qualcomm.com/products/snapdragon/quick-charge

So anyone tried it? That is the question
Yes, I have the Motorola Turbo Charger.

How long does it charge from 0-50 from50-100 from 0-100?
There aren't many chargers out there. and the ones that are, are usually US 2 pin. I need a UK 3 pin or travel charger (changeable pins) really.

To achieve full charging speeds, a Quick Charge 2.0 enabled device must be paired with a Quick Charge 2.0 certified adapter
Hey guys,
So I got this Samsung wireless charger that is supposedly 'original' from Aliexpress.
There's actually a fan inside and it does say that it's fast wirelessly charging on the phone. However it is not that fast - 15% in 40 minutes. What speeds do you get with your wireless chargers? I'm using the original wall adapter from Samsung (9V 1.67A one).

If it cost less than from the samsung store then its not original, it does take 4 hours to charge the phone with the cheap wireless charger.
Of the ones I've used even with my S5, I found the cable and power supply are critical. Lastly the placement on the charger. All of mine have come from an Aliexpress seller. I can't tell you exact times but I know they charge as fast as the phone will allow before overheating. Not to say some sources aren't bad. Just my luck has been good. I even converted some of my S5 vehicle charge pads, simply by adjusting the charge center, and have continued to use them. Anyway, try different cables and usb supplies. if the phone doesn't get warm or better it isn't charging fast.
